SPECIFICATION forming part of Letters Patent No. 474,599, dated May 10,1892.

Application filed November 4, 1891. serial No. 410,314. (No model.)

To aZZ whom it may concern:

Be it known that I, JOSEPH FRITZ, a citizen of the United States,residing at Baltimore city,in the State of Maryland, have inventedcertain new and useful Improvements in Suspender-Buckles, of which thefollowing is a specification.

This invention relates to an improvement in suspenderbuckles; and theobject is to provide a buckle which in its use will not tear thesuspenderwebbing and which cannot loosen its hold on said webbing untilmanipulated in the proper manner.

To this end the invention may be said to consist in the novel featuresof construction and combinations of parts hereinafter described andclaimed.

In theaccompanying drawings, which illustrate my invention, Figure 1 isa front View of the buckle. Fig. 2 is a rear View. Fig. 3 is a side oredge View. Fig. 4 is asimilar view showing the position of the partswhen the buckle is released from the webbing. Fig. 5 is a verticalsection showing the suspender-webbing clamped by The buckle, and Fig. 6is a cross-section on line 6 6 of Fig. 1.

The device comprises a triangular plate A, having one edge turned up andserrated, as shown at a, and an inturnedear Z) at each end of saidflange. A rectangular wire frame or bail B is hinged to the plate asfollows: A side bar 0 of the frame extends across the plate below theteeth a and passes through the ears I), in which it may turn. Thecentral part c of this bar is bent inward, so that it may be broughtclose to the plate. The end pieces (1 of the frame have position on 1the outer side of the ears b,and between them and the bar 0 elongatedloops 6 are formed out of the frame-wire, which loops extend at rightangles to the said bar 0 and constitute cranks for turning the frame onits pivots, as will hereinafter appear. These loops extend on a downwardangle to the side pieces of the frame and work close to the earslb.Their lower ends receive inturned trunnionsf of a wire frame C, the sidepieces or wires 7) of which extend downward and converge. They cometogether at the lower part of the triangular plate A and thence extenddownward side by side and are together turned or bent up to form a hookD, which takes the ring E and bent downward to extend behind the end ofthe hook for the purpose of holding the ring of the suspender-end in thehook, and this tongue is of sufficient length to allow a slidingmovement of the frame 0 over the face of the plate.

In the use of the buckle the hinged frame Bis turned down to theposition shown 111 Fig. 4 and the suspender-webbing F is introducedbetween the teeth a and the centralinbent portion of the bar 0. Theframe is then turned up against the webbing, and 1t will be seen thatthe inbentportion 0 will be forced against the webbing of thesuspenderand w ll bind the same down over the teeth a, (see F1g. 5,)whereby it is securely held. In this operation of the buckle the portion0 of the frame serves as a rock-bar, the upper portion of the frameconstituting a handle by which it is turned. This rock-bar, by reason ofits bent central part, behaves like an eccentric or cam to bind thewebbing over the teeth of the plate. It will be observed that theswinging down of the frame B causes the sliding up of the frame G byreason of the crankloops e being raised by the turning of the bar 0.Hence it will be apparent that a downward pull on said frame 0, actingon said crank-loops, will draw the hinged frame 13 to its uprightposition and turn the binding-bar a, so as to force its central part 0against the suspender-webbing. Thuswith the suspenders applied thebuckle can never release accidentally from the webbing, for there isalways a downward strain on thehook through the ring E of thesuspender-end. The downward angle of the crank-loops assists thisbinding function of the bar 0 because it keeps the trunnions f always atthe outer extremity of said loops, whereby the greatest leverage isobtained. By arranging for the toothplate to remain stationary I avoidthe tearing of the webbing incident to the use of a hinged tooth-plate.

a rock-bar extendinglengthwise ofsaid plate and journaled in theinturned ears, the central part of said rock-bar bent and forminga camand the bar having cranks on its ends and a suitable handle for turningit, and a depending frame jointed to said'cranks and constructed toconnect with a suspender-end 2. A suspender-buckle comprising -a platehaving a toothed flange along one edge and inturned ears at oppositeends of said flange, a hinged frame one side of which constitutes arock-bar extending lengthwise of saidplate and journaled in the inturnedears, the central part of said rock-barbent and forminga cam and theframe having crank-loops at the opposite ends of the rock-bar, and adepending frame having trunnions engaging in the ends of said crankloops and constructed to connect with a suspender-end.

8. A Suspender-buckle comprising a plate having a toothed flange alongone edge and inturned ears at opposite ends of said flange, a rock-barextending lengthwise of said plate and journaled in the inturned ears,the central part of said rock-bar bent and forminga cam and the barhaving cranks on its ends and a suitable handle for turning it, and adepending frame jointed to said cranks, two side pieces of said framebrought together to form a hook and held together by portions of theplate bent over them, a portion of said plate also forming aspring-tongue extending past the end of the hook, for the purposedescribed.

In testimony whereof I affixmy signature in the presence of twowitnesses.
